This thesis introduces the working principle, craftwork requirement, modeling process, control strategies and the realization of lf refining furnance bottom blowing argon control system. through the study and analysis of bottom blowing argon process control system, the thesis discusses the mean neural network model of controlled object and the mathematical models of the exectors, pwm adjustable pressure controller and pcm adjustable flux controller according to the relevant liquid knowledge and relevant data, including design data, test data and running data. to begin with the craftwork reguirement of bottom blowing argon and the actual instance of the control system, it presents the strategies of fuzzy parameters self - adaptive pid control used in pressure difference inner loop and fuzzy plus pi compound control used in flux outer loop which are based on the above modeling in order to carry out the accurate control of argon flux
本文介紹了lf精煉爐底吹氬過程式控制制系統的工作原理、工藝要求、建模過程、控制策略以及控制系統的實現。通過對精煉爐底吹氬過程式控制制系統進行研究與分析，並根據流體力學的有關知識以及有關數據（其中包括設計數據、試驗數據和運行數據） ，建立起了被控對象的平均神經網路模型和執行機構（即pwm調壓器和pcm調流器）的數學模型。在此模型的基礎上，從底吹氬工藝要求和控制系統的實際情況出發，提出了壓差內環模糊參數自適應pid控制策略和流量外環模糊pi復合控制策略，以實現氬氣流量的精確控制。At the end of the experiment, we reconstructed the subsystem of second air measuring, i. e. we used airfoil measuring equipment as a replacement of original equipment of flute pipe. we also demarcated the velocities of spouts of burner which can deal with correlative data, and which can provide some help for operation
最後又對監測系統二次風測量子系統進行改造，將原笛型管裝置修復為機翼測風裝置，對傳感器進行差壓標定;在爐內噴口處標定速度，將數據進行處理，提供給熱工控制顯示用，對運行調整提供了幫助。Thedeviation was caused by the influence of the condensate temperature in the equalizer andthe positive / negative sampling tubes as well as by the effect of the high ambienttemperature
對此，分析了鍋爐水位偏差的原因有平衡容器內凝結水溫度問題，正負壓取樣管內凝結水溫差的問題及環境溫度高的問題。For the problem that on - line monitoring of primary air of direct firing pulverizing system ca n ' t be complete achieved, the chaotic properties of parameter change of two - phase flow in pipe is analyzed in the paper, according to the pressure difference signal of two - phase flow system
目前電站鍋爐直吹式制粉系統的一次風氣固兩相流流動狀態在線監測仍未得以實現，針對這一難題，本文首次基於管道內氣固兩相流差壓信號對其流動狀態變化的混沌特性進行理論研究。分享友人
